becker cdr 220 radio code

[Soshman]

Just bought a 2002 Boxster...not my first Porsche (I am a big fan of 964s, had a couple) and need the code for the replacement CDR 220, the original does the initial POSRCHE thing, asks for the code, which I input then it does the WAIT thing which I am familiar with...and then I go through the same cycle again.

So, replacement in hand and the serial number is 15003770.

Thanks for any help you can provide.

Once done I will begin the new/replacement key saga!!!!
